A matsayin kayan da aka saba amfani da su a cikin masana'antu daban-daban, cellulose ether foda yana da kyakkyawan mannewa, daɗaɗawa da riƙewar ruwa. An yi amfani da shi sosai wajen gine-gine, magunguna, kayan kwalliya, abinci da sauran fannoni da dama. Duk da haka, don samun mafi kyawun aikin daga cellulose ether foda, dole ne a biya hankali ga tsarin rushewa. Anan akwai wasu mahimman abubuwan da za a yi la'akari da su lokacin narkar da foda ether cellulose:
1. Zabi madaidaicin ƙarfi
Cellulose ether foda yana da narkewa sosai a cikin ruwa, yana samar da haske, bayani mai danko. Duk da haka, daban-daban na cellulose ethers suna da daban-daban solubility a cikin ruwa, kuma su solubility za su shafi abubuwa kamar zazzabi da kuma pH. Saboda haka, zabar madaidaicin ƙarfi don sakamako mafi kyau yana da mahimmanci.
Alal misali, idan cellulose ether foda yana buƙatar narkar da shi a cikin ƙananan yanayin zafi ko a cikin ƙananan tsarin pH, hydroxypropylmethylcellulose (HPMC) ko methylcellulose (MC) na iya zama mafi kyau fiye da ethylcellulose (EC) ko carboxylate Better Choice Methylcellulose (CMC). Yana da mahimmanci don zaɓar ƙaushi mai dacewa la'akari da buƙatun aikace-aikacen da kaddarorin ƙarfi.
2. Sarrafa zafin jiki
Zazzabi shine wani mahimmancin mahimmanci wanda ke shafar rushewar cellulose ether foda. Solubility na cellulose ethers yana ƙaruwa tare da zafin jiki, amma haka ma yawan rushewa, wanda zai iya haifar da raguwa ko raguwa. Sabili da haka, dole ne a kula da zafin jiki a hankali yayin aikin rushewa.
Gabaɗaya magana, mafi kyawun zafin jiki don narkar da ether cellulose shine 20-40 ° C. Idan zafin jiki ya yi ƙasa sosai, yana iya zama dole don tsawaita lokacin rushewa ko amfani da sauran ƙarfi mai dacewa. Idan zafin jiki ya yi yawa, zai iya haifar da lalacewar ether cellulose kuma ya shafi aikinsa.
3. Dama da motsawa
Har ila yau tashin hankali da tashin hankali suna da mahimmanci lokacin narkar da foda ether cellulose. Tashin hankali da ya dace yana taimakawa foda ya watse a ko'ina a cikin sauran ƙarfi kuma yana hana kumbura. Har ila yau, motsa jiki yana taimakawa wajen ƙara yawan rushewa, musamman ga mafi yawan matsalolin danko.
Koyaya, tashin hankali da yawa na iya haifar da kumfa ko kumfa, wanda zai iya shafar tsabta da kwanciyar hankali na maganin. Sabili da haka, wajibi ne don daidaita saurin motsawa da ƙarfi bisa ga ƙayyadaddun buƙatu da yanayin aikace-aikacen cellulose ether foda.
4. Additives
Ana iya ƙara abubuwan da ke daɗaɗɗa yayin rushewar cellulose ether foda don inganta aikinta ko kwanciyar hankali. Misali, ana iya ƙara borax ko wasu abubuwan alkaline don daidaita pH na maganin kuma ƙara danko. Sodium bicarbonate kuma yana ƙara danko na maganin, yana rage yawan rushewa.
Ana iya amfani da wasu abubuwan da ake ƙarawa kamar surfactants, salts ko polymers don haɓaka solubility, kwanciyar hankali ko wasu kaddarorin maganin ether cellulose. Koyaya, yana da mahimmanci a yi amfani da ƙari a cikin matsakaici kuma zaɓi a hankali, saboda ƙari ko abubuwan da ba su dace ba na iya haifar da lahani maras so.
5. Lokacin narkewa
Lokacin rushewa shine muhimmin ma'auni a cikin samarwa da aikace-aikacen foda ether cellulose. Lokacin rushewa ya dogara da dalilai da yawa kamar nau'in ether cellulose, ƙarfi, zafin jiki, saurin motsawa da maida hankali.
Gabaɗaya, cellulose ether foda ya kamata a ƙara shi zuwa ga kaushi sannu a hankali kuma a hankali tare da haɗuwa akai-akai har sai an sami bayani mai kama. Lokacin rushewa na iya bambanta daga ƴan mintuna zuwa sa'o'i da yawa, ya danganta da abubuwan da aka ambata a sama.
Yana da mahimmanci don saka idanu a hankali tsarin rushewa da daidaita sigogi kamar yadda ake buƙata don tabbatar da inganci da daidaito na ether cellulose.
A ƙarshe, cellulose ether foda abu ne mai mahimmanci kuma mai mahimmanci a fannonin masana'antu daban-daban. Koyaya, tsarin rushewa yana da mahimmanci don cimma kyakkyawan aikin sa. Ta hanyar kula da abubuwa kamar zaɓin ƙarfi, sarrafa zafin jiki, motsawa, ƙari, da lokacin rushewa, yana yiwuwa a sami ingantaccen ether ether cellulose wanda ya dace da bukatun aikace-aikacen.
